In its general organization this barrel making machine comprises means Afor setting up the staves in the VAform of 'a barrel preparatory to drawing them together; Windlassing means for drawing the staves of the barrel together into the `form of ya tubular body or shell gmeans Vvfor driving or trussingthehoops on the `body or shell of the barrel .after the latter has been heated; means for producing the croze or chine, and cha-infer on the v.ends of 'the barrel and trimming oil" `these ends; and means for driving these several mechanisms and controlling .the operationv of .the same.

Star/ve setting up mechanism,

The staves of this barrel shell or body are tapered from their side central parts toward their opposite ends, Ysimilar to those now common-ly employed in slack cooperage. The mechanism whereby a plurality of Such staves are set up and dra-Wn together in the form of a shell 'can be of any usual and well known construction, such as .by a-Windlassing mechanism having a Windlassing ropeadapted to :embrace the staves of the barrel and draw them together into the form of a barrel shell. I

After the upper ends of the staves of the barrel have been drawn together Yor contracted by Vthe lWindlassing .mechanism so that thie shell or shody vofthe barrel is of substantially tubular form, vhut having a hilge lin its center, the operator places Aa temporary or trussingen d hoop 106 on this end ofthe shell before releasing the Windlassing rope and then loosely applies :a permanent bilge hoop 107 upon the end of the shell or body adjacent to the hilge thereof. The shell having the temd porary end hoop and the permanent bilge hoop applied thereto is then placed in an upright position with one end resting on the base of the machine in proper position rela-- tive to the hoop trussing 01 driving mechanism which is constructed as follows:

Arranged above that part of the base supporting the barrel to be trussed is a vertically movable cross head 108 which is secured on opposite sides to the upper ends of two vertically movable gear racks 109. The latter are guided at their lower ends in tubular columns 110 which rise from the base on opposite sides of the barrel body or shell supported on the base. rl`hese gear raclzs together with the parts mounted thereon are caused to rise and fall by a lifting mechanism which comprises gear pinions 111 meshing with the gear racks 109 and mounted on short shafts 112 which are journaled on the upper mds of the columns 110, as best shown in Figs. 3 and 5; gear wheels 113 secured to the shafts 112; intermediate shafts 114; je' rnaled in upright side pieces 115 of the main frame and provided with intermediate or gear wheel pinions 116 meshing with the gear wheels 113 respectively; and a transverse equalizing shaft 117 journaled in suitable bearings on the side pieces 115 and provided at opposite ends with gear pinions 118 which mesh respectively with the intermediate gear pinion 116; and means for causing` the equalizing shaft 117 to be turned alternately in opposite directions by motion derived from the motor shaft 92.

.The mechanism whereby the transverse equalizing shaft 117 is thus caused to turn alternately in opposite directions while the motor shaft turns continuously in the same direction, may be of any approved form, that shown in the drawings-see particularly Figures 1, 3, 5, and 6 being constructed as follows:

The numeral 119 represent-s a wide belt pulley secured to the transverse shaft 117, and 120 and 121 represent two driving belts passing around opposite enos of this vite driven pulley 119, the opposite turn of the belt 120 passing around a driving pulley 122 on the motor shaft 92, while the opposite turn of the driving belt 121 passes around a driving pulley 123 which is secured to a counter shaft 124 journaled in suitable bearings on the adjacent part of the main framel The numerals 126 and 127 represent two intermeshing gear wheels or pinion-s of the same size secured4 respectively to the motor shaft 92 and counter shaft 124, as shown in Fig'. 3v1 whereby these shafts are caused to turn in opposite directions. lt follows therefore that when the belt 120 is tigthened and the belt 121 is loosened, then the gear pinions 111 will be turned in one direction, while upon loosening the belt 120 and tightening the heit 121, said gear wheels 111 will be turned in V the opposite direction, but when both of these belts 120, 121 are loose then no motion Will be transmitted to the gear pinions 111 and the gear racks and the parts associated therewith will remain at rest.

rlhe tightening and loosening of the belts 120, 121 is preferably effected by means which comprise a rock shaft 128 which is arranged horizontally and transversely in rear of the barrel supporting part of the base and journaied in bearings which are arranged on the base and which may be of any suitable character, and tightener arms 129, 130 projecting in opposite directions from the rock shaft 128 and provided with tightening pulleys 131 and 132 respectively, which are adapted to bear against the belts 120 and 121. 1n the central position of the rock shaft 128, both tightener pulleys 131 and 132 are disengaged from the belts 120 and 121 so that no motion is transmitted from the motor shaft 92 to the mechanism which raises and lowers the main cross head 108. Upon rocking the shaft 128 in the direction for engaging the tightener pulley 132 with the belt 121 and still holding the other tightener pulley 131 out of engagement from the belt 120, then motion will be transmitted from the motor shaft 92 to the racks 109 so as to move the cross head 108 and the parts mounted thereon downw lly. Upon rocking the shaft 128 in the opposite direction so as to disengage the tightener pulley 132 from its companion belt 1.21 and engaging the tightener pulley 131 with its companion belt 120, then motion will be transmitted from the motor shaft 92 to the gear racks 109 for the purpose of raising the cross head 108 and associated parts mounted thereon.

The turn of the rock shaft 128 in either direction from ay central or neutral position is effected by means of a hand lever 133 which latter is so connected with this shaft 128 that the same will normally remain in its central or neutral position and must be forced by manual pressure downwardly if it is desired to lower the main cross head, and to be forced upwardly manually out of its neutral position when it is desired to raise the main crosshead.

During the 'descent of the cross head 108 the first part of this motion is utilized to complete the driving of the upper bilge hoop on the shell and the second part of this movement is utilized for completing the 'driving of the upper end hoop on the same. If it is desired, the bilge hoop may be either a permanent or 'temporary truss hoop but for the ut purposes this distinction can be disded as the use of a temporary or perma- .nent hoop is a matter which is governed by choice and by differing conditions.

rflic numeral 156 represents a plurality of upright driving arms which are arranged in in annular row around the cross head 108 and each of which is pivoted thereto at its oppolll) site ond by' meansofi a. horizontal pivot bolt 15'? sothat the drivingdie orjaw 158 at the lower end of eaeh driving' arm. may be moved toward Yand from the periphery od the' barrel shellV orhodly and into and ont of ongegeinent' with the upper' edge of: the. upper bilge hoop.; 'Ehe several driving arinsf are moved inwardly preparatory to 'engaging with tlrfe 162.A The outer end of eaclr shifting roel is yieId'i-ngl'y connected with one' of the driving arms below the n-lernm of the latter hy slidingly' engaging the1 outer part of each rod 162 with its guide lug's1163 on the' respective driving" erin, and interposing a springv 164 be'- tweerr the innerguide lug' 163 and the inner side of collar 165 on the respective shitting roel. Upon turning' the driving disk 159 by' means of' a' han-olle 166'- in'- one direction, the several crank pins 161 on tlri's disk will cause' the shifting' rods 162 to draw the driving arms 156V inwardly and engage the periphery of the' barrell immediately above the upper bilge hoop thereon.

After tlf-e opera-tor has turned' the Crank dise 159 soasftoshift the driving'dies or jaws` into tlie' proper' positionrelative to the periplrery of the barrel,'the operator works the lever 133r so as' to cause the eross head to desee-nd whereby'the dies or jaws of the drivl ing arms' are caused to' engage the' upper` edge of tbe bilge hoops and dri-ve the same'- downwardly on the shell or body of the barrel until it is tight, after whichtlie operator re'-v ve'rse's the throwof' the crank disk 159 and causes the drivin-g dieser jaws 158 to be dis'- en'gaged from-tlrebilge' ho'op. Thereafter' the operator again `mani-pulate's-tlie' controlling lever 133 so` as to cause the' crosslie'ad to ef feet the' second and final part of its downward movement for the purposeA of engaging a driving' ring or' flange' 173'w'it'l1 the upper edge' of the upper temporary or truss hoo-p, as sliown in- Fig. 6.y l I Thisdriving ring is formed on inner lower` part of a eiroular'rim 174 which .1sl secured tothe underside'l of' tlieinain cross head 108. 'During the last" stepof this descending movement of the main erosslread, the upper end of the barrel is centered by engagement w therewith of a plurality' of downwardly diverging` centering fingers' 175 secured to the lower edge of: the supporting rim 17e-and adapted to engage with the upper peripheral A barrel shell or body, as shown in Fig. 6. Dur'-V fas ing the final portion of the downward move-- ment oi the orosshead, the driving' arms and the driving dies or jawsat. their lower ends are disengaged from. the adjacent bilgehoop and'. move idly downwardly' beyond this ,I so that only driving'ring 173-at1 thisltime performs any function.-

Umain-g, /imferz'ng and trimming mechanism While the cross' head. or carrier 108 is its lowerrnos't position and the' barro]l is being' lieldi in its' @entered position'. by ein gagenient of the driving' hoop ring 173 'with the upper end hoop, the' operator brings `into aeti'o'nlthe rneelrani'sin which cuts" a Croze' and oliamfer on the* upper' enid of the barrel shell and also trims off this' end'7 which mechanism, is constructed as' follower' The numeral 176 represents' upright hollow shait which is" jonrnaled in a bearing 177 arranged eentr'elly on the cross' hond. 1.08' and iin/axial alignment @if eon'eenilrieal wilt'lfl the axis oat the barrel. slrell` which is' to be operated upon. et its lower end, this shaft is provided with a laterally projeeting' arm: 12T-8, the underside of which isf provided with a`- not'eh 1'791- Ii this notc'll is'. adjustalily se"A Cured' a su l'porti'n'gng' member 180' having the" fori-nef a bar which can slid tange'ntially' relatively to the' axis of' tlieshaft' 176 for' the' purpose of bringing' partswhie'li are' mount.- e'd' on the outer end of this bar into position with referene'eto thefbarrels of different sizes or diameters; Y l

After Vadjustinent this bor' or' supporting member 180 is secured in place by means of' a clamp-ing plate181 bearing' against the. un derside of this'barV and seen-red to the arm 1718 by' means of'a clamplng bolt 182. Upoirthie outer end of this supporting' bar" 180 are moon-ted two pairs of paralleli levers 2117 wli-iehare aclaptedlto turn about? vertical axes so that tlreir movement ilsV in planes at right angles to theiaxis of the vertical slraftrll'.

1n'- tlie preferred eon'str'u'etio'nf. a; pair' o f these levers ifs' arranged on the upper side ot the harlSo and another pair on the underside of the same and the: corresponding' levers are' connected hy' pivot pins V183 with the snpporting bar 180;- as best shown. in Fig. 15.

Between the' corresponding ari'nsi on one side of' these levers is arranged e parallel block 184 which is pivotaflily connected therewith byu-leans of' vertical pivot pins 185 and hetweenthe opposite armsothes'e levers is ar'- rangedanother parallel block 186 which i's' pivotedrthereto by means of vertical bolts 187' as shown in' FigA 1.6L 'lhes'e parallel. leveil-sI 217 andi bloeks therefore form. a double porallelograrn. which @euses these blocks to always remain in a: parallel position with referenee to each other upon'. swinging' the parallel levers 217 horizontally.

' 0n the 'underside of the. parallel. block 184' the. some-is provided with aseait188 sgrinst which a croze cut-ter 189 is adapted to be clamped by means of a clamping block 190,

as shown in Fig. 13, and on its upper side this parallel block is provided with a seat 191 `against which a chamfer cutter 192 is held by means of a clamping block 193, as shown in the same figure. rIhe croze cutter is preferably constructed in the form of a gouge or gouging bit which is of substantially V- shape form in cross section so that upon engaging the inner side of the shell adjacent to the end thereof, a croze 194 will be cut in the shell, as shown in Fig. 11. The cutter or blade 192 is flat and inclined upwardly and 1 also tilted laterally so that when its front cutting edge engages with the inner side of the barrel shell between the croze 194 and the end of the barrel a chamfer 195 will be formed on the shell, as bestshown in Fig. 10.

The two clamping blocks 190,193 are firmly drawn against the outer sides of the cutters 189 and 192 by clamping bolts 196 passing through these blocks and the parallel block 184, upon which these cutters are mounted,

'- as shown in Fig. 13.

Upon the upper side of the other parallel block 186 is mounted the inner end of a cutter supporting bar 197 which latter supports at its outer end a cutter or blade 198 which is adapted to trim or cut off the end of the barrel shell for the purpose of finishing the same, as shown at 204 in Fig. 12, and establishing the correct length and height thereof.

In order to permit of adjusting this edge trimming knife 198 for adapting the machine to cut barrels of different diameters, the supporting bar 197 is mounted adjustably on the parallel block 186, this being preferably accomplished by means of adjusting bolts 300 passing through the parallel block 186 and through longitudinal slots 199 in the supporting bar 197, spacing sleeves 200 being mounted on the clamping bolts 300 between the upper side of the parallel block 186 and the underside of the supporting bar 197, as shown in Fig. 16, for the purpose of avoiding interference between these several members.

In its preferred construction the end trimmer is made in the form of the letter C in order to permit a cutter of suflicient length to be employed which can be placed in the narrow space available for this purpose and still provide suflicient length of cutter which will permitof advancing the same as itsV front cutting edge becomes worn and requires repeated sharpening. For this purpose the end trimming cutter 1s mounted on a cutter block 201 so that the same is capable of adjustment about the axis or center of its curvature, whereby this cutter on being turned about this axis can be adjusted so as to bring its front or cutting edge in the proper position relative to the edge of the barrel and thus permit of compensating for wear and sharpening which is required from time to time. This end cutter is firmly held in its operative position on the cutter block 201 by means of a clamping block 202 and a clamping bolt- 203 whereby this cutter block 201 and clamping block 202 are firmly drawn against opposite sides 0f this end cutter, as shown in Figs. 9 and 12.

While the cross head 108 is being lowered over the upper end of the barrel shell, the parallel levers are turned so that the Croze and cham'fer cutters are moved inwardly and the edge trimming cutter is moved outwardly, in which position these cutters will clear the edge of the barrel shell, inasmuch as the eroze and chamfer cutters are at this time arranged on the inner side of the barrel shell and the trimming cutter on the outer side of the same, as shown in Fig. 8. Upon turning the parallel levers 217 in the opposite direction, the Croze and chamfer cutters Will be engaged with the inner side of the barrel shell at the upper end thereof and the end trimming knife or cutter 198 will be moved inwardly across the upper end of the barrel shell, whereby these cutters upon being rotated with the shaft 176 will simultaneously operate to produce the Croze, chamfer and end trim on the barrel shell.

This movement of the parallel levers 217 for the purpose of shifting the cutters into and out of their operative position may be effected in various ways, but preferably by the means which are shown in the drawings and which comprise a vertically moving shift rod 205 which slides within the bore of the shaft 176, a shifting linkage 206 p ivotally connected at its inner end with the lower end of the shifting rod 205 and pivotally connected at its other end with the parallel block 184, and a hand lever 207 operatively connected with the upper end of the shifting rod 205. When the shifting rod 205 is in its lowered position the linkage 206 operates to draw the parallel block 184 and the cutters 192 and 189 inwardly away from the end of the barrel shell and the end trimmer .198 outwardly away from this shell, but when the shifting rod 205 is raised into the postition indicated by full lines in Fig. 14, the parallel levers l217 and blocks are shifted in the direction for moving the croze and chamfer cutters outwardly and the trimming cutter inwardly into the operative positions.

The preferred construction of the linkage 206 comprises two separate links which are arranged on opposite sides of a coupling block 208 which is secured to the lower end of the shifting rod, these links being pivotally connected with this block and also capable olf `by gravity.

against an adjusting screw 214 arranged on the block 211, as shown in Fig. 14.

By this means an adpistment of the cutter mechanism withreferenceto its actuating 1 orV shiftin g mechanism may be effected for the purpnose of adapting the cutters for opera-jing 0n- Varrel shells of d iderent diameters, a

coarse adjustment being first effected by shifting the pivot pin 209 from one set of holes 210 to another and then following this with a `fine adjustment which is accomplished by turning the screw 214 in one direction or the other.. This screw 214 is constantly held against the pivot pin 212 by a spring return device which also operates tomove the cutter blades away from the end of the barrel whenever the downward pull upon the hand lever 207`is released and the shifting rod 205 is per'- mitted to drop into its inoperative position This, spring device as best shown lin Fig. 13 preferably consists ofa, swivel 215v which is pivotally mounted by means of a pin 216 on extensions of two of the parallel levers `217 anda spring 218 bearing at one end against thisv swivel 215, while its opposite end bears against the bottom of a socket 219 formed on the adjacent part of the parallel block 184. llVlien the cutter mechanism is operated to engage the blades with the endr of the barrel thenZ thespring 218 is placed under increased tension and when the cutter mechanism is released by `dropping of the shifting rod 205 and releasing of the hand lever 207, then the resilienceof the spring 218 operates to move the cutter mechanism in the direction for disengaging the blades from the end of the barrel.

The hand lever 207 may be supported in any suitable manner but preferably by means of a link 220 which is mounted on the cover 221 of a casing 222 arranged above the upper end of the shaft 176 and forming in edect a part of the cross head 108 upon which it is mounted, as best shown in Figs. 5 and 6.

While the cutter mechanism is lowered upon the upper end of the barrel and its blades are movedinto engagement therewitlna rotary movement is Iimparted to the shaft 176 so as to cause these blades to cut the croze and chamfer on the barrel shell and trim the end thereof. For this a manually controlled driving mechanism is employed whereby motion is transmitted from the motor shaft 92 to the driving shaft 176 ofthe cutter mechanism. This driving mechanism in its preferred form and as shown in Figs. 1, 3 and 6 is constructed as follows:

The numeral 223 represents-.a worm wheel secured to the upper end of the cutter shaft 176 within the housing 222, andthe numeral 224 represents a worm` meshing with .said worm wheel and. mounted upona shaft 225 which is journaled in suitable bea-rings on the adjacent part of the casing` 222. -At one end of Vthis worm shaft 225' is provided a hand wheel 226J whereby the same may be by hand while adjusting. or setting up r mechanism and on its opposite. end Ithis shaft is provided with a driven Vpulley which is adapted to receive power from the motor shaft .92.

The numeral 228 represents a. 'driving pulley mounted en .the motor shaft 92 and"229 `nd 230 represent two intermediate pulleys er of the main cross head and the cutter iafit 176 journaled thereon. The lower termediate pulley 229 is journaled on` a aring mounted on the upperend, of a post 1rod which risesf'rom the adjacent. Part f the base 75, and the upper intermediate -oulley has its axle. 233-suspe1rdedby means Q link 234 on the upper end of. this post.

oi a The numeral 235 represents a' drivingfbelt passing with its Vlower turn around the driving pulley 228 and .withits upper turn around the driven pulley 227,. while` the intermediate part of one of its stretehes. ,pas`ses over the lower intermediate pulley 22,9. and the intermediate Vpart of its. other stretch passes around the other intermediate pulley 230. rlhe upper intermediate pulley 230, serves as a belt tightener with vreference to the, belt 235 so that by moving this pulley 23.0. downwardly into a position in which it leavesttliis beltslack, as shown by full lines in Fig.` 1, then no power will be transmitted from the motor shaft 92 to the cutter shaft 1.765! but when this tightener pulley 230 has, swung backwardly `and upwardly .thedriving belt 2:35 will be tightened, as shown by dotted lines in Fig. 1, and thereby cause motion to be transmitted from the motor 91 to the cutter mechanism.` The intermediate pulley 230 is moved into, and outof its opera.- tiv'e position for tightening or loosening the belt 235 by means of aishipper rod or bar` 236 guided midway of its ends in a vbracket 2,37 arranged on the upper side of the cross head 108 and provided atY itsl front end with a handle 238 while vits rear end is, connected with thelower end of the link 2.34 which supports the tightener pulley 230. .Upon pushing the shipperrod or bar 2.361 backwardly the belt 235 is tightened Jfior (railsifrlg.the.Cut`- ter mechanism to operate, vand upon moving this bar forwardly this belt is loosened and the` cutter meclfianismV ceases its operation.

After the bilge and end hoop have been driven on one end of the. barrel shell, andthe croZing, chamfering and trimming operations havebeen performed on the. respective end v1'anged above the motor shaft 92 and in tightener of the same, the barrel shell is reversed end for end and similar operations are performed on the other end of the barrel shell which is now uppermost, while the reversed finished end is now resting on the base of the machine.
